哪错了？？？

#include<bits/stdc++.h>
using namespace std;
struct abc{
    string a;
    int b;
    int c;
    int d;
};
abc m[1000];
int main(){
    string k;
    int n,q,w,e,o=0;
    cin>>n;
    for(int i=0;i<n;i++)cin>>m[i].a>>m[i].b>>m[i].c>>m[i].d;
    for(int i=0;i<n;i++){
        if(m[i].b+m[i].c+m[i].d>o){
            o=m[i].b+m[i].c+m[i].d;
            q=m[i].b;
            w=m[i].c;
            e=m[i].d;
            k=m[i].a;
        }
    }
    cout<<k<<" "<<q<<" "<<w<<" "<<e;
    return 0;
}
